Standard raised floor

The invention relates to a floor, especially a standard elevated floor with a rib structure.

At present, in semiconductor factories, elevated floors with multiple micro-perforations are installed to clean the air quality of the environment and ensure the clean room specifications.

At present, the raised floor system is made by mold casting. In the molding process, the required product is often made by a mold, and before the molding operation, a release layer will be coated on the mold to facilitate the subsequent demoulding operation.

However, it is known that the structural strength of the raised floor is often insufficient, so when the raised floor carries heavier equipment in the semiconductor manufacturing process, the raised floor is prone to breakage. On the other hand, there is also the problem that the raised floor is too heavy, which not only wastes materials, but also increases the manufacturing cost.

Therefore, how to overcome the problems of the above-mentioned conventional technologies has become a difficult problem to be overcome urgently in the industry.

For example, the foot 1b is used to adjust the total height H of the standard raised floor 1 so that a plurality of standard raised floors 1 are located at the same level.

Furthermore, the ground side 10a is a flat surface, and the recesses S are arranged in an array to form a plurality of thimble positions 1c (approximately in a square area formed by every four recesses S) on the honeycomb side 10b. The corner of the above) honeycomb structure.

The rib structure 1a is defined in sequence from the edge of the top plate 10 to the middle (or from the left and right sides to the middle as shown in Figure 1B and Figure 1C ) with a first rib 11, a second rib 12, and a third rib 13. The fourth rib 14, the fifth rib 15, the sixth rib 16 and the seventh rib 17, and the first, second, fourth, fifth and seventh ribs 11, 12, 14, 15, 17 are relative to The heights h1, h2, h4, h5, h7 of the honeycomb side 10b are at least 25 millimeters (㎜), and the heights h3, h6 of the third and sixth ribs 13, 16 relative to the honeycomb side 10b are less than 25 mm, so the first, second, fourth, fifth and seventh ribs 11, 12, 14, 15, 17 are the main ribs, and the third and sixth ribs 13, 16 are the middle ribs , wherein, the first to sixth ribs 11-16 are distributed symmetrically (or vertically symmetrically as shown in FIG. 1B ) based on the seventh rib 17 (square rib), so that the second rib 12 , The distance w between the third rib 13 , the fourth rib 14 , the fifth rib 15 , the sixth rib 16 and the seventh rib 17 is 48 mm.
